About Sudoku
Play Sudoku, the classic number puzzle — anytime, anywhere, fully offline. Fill the grid so every digit 1–9 appears exactly once in each row, column and 3×3 box!
How to play
Every puzzle is freshly generated and guaranteed to have exactly one solution. Tap a cell, pick a digit and use pencil notes for candidates. Mistakes show up immediately; three mistakes end the game.
Four difficulty levels
- Easy: plenty of digits filled in, perfect for a quick break
- Medium: the classic newspaper puzzle
- Hard: for the practised solver
- Expert: minimal help — for the true puzzler
Adventure mode
Play through hundreds of numbered levels that get progressively harder. Travel through colourful worlds, earn a medal on every level and grab milestone rewards along the way.
Daily puzzle
One unique sudoku every day, the same for everyone. Earn a medal of 1 to 5 stars and build a streak: 3, 7, 30 or even 100 days in a row!
Coins and themes
Earn coins with every completed puzzle and spend them on hints or new looks: Forest, Space, Neon, Wood, Marble, Christmas and Halloween. Cosmetic only — no pay-to-win.
